摘　　要：为了减少驱动程序中存在的缺陷对系统运行造成的严重影响,研究并实现了一种在操作系统内核的基本部分与设备驱动程序之间增加"驱动隔离层"的内核驱动隔离机制,同时提供驱动程序发生故障后的检测及恢复机制。这种将驱动程序隔离运行的机制明显区别于传统的操作系统,能够对系统内核区域进行严格的访问控制保护,避免了由于驱动程序存在缺陷所导致的系统失效。实验结果表明,该内核驱动隔离系统有效地提高了系统的可用性,同时对用户和应用程序透明,具有良好的兼容性。In order to reduce the serious impact of the defects in driver when the system is running, an isolation strategy is de- signed and implemented to insulate the kernel essential part and device driver by adding the driver isolation layer in kernel space, which at the same time provides the self-healing environment and driver failure recovery mechanism for the faulty drivers. This operating environment has changed the traditional mode of operation of the operating system, which protects system kernel area, and avoids system failures due to driver error. Experiments prove that the kernel driver isolation method improves the availability and security of system effectively with good compatibility, while transparent to users and applications.
